VSpecification of Letters Patent.

Patented Mar. 9, 1915.

Application led July 3, 1911. Serial No. 636,805.

T0 all 'whom t may concern Be it known' that I, EDWIN G. STAUDE, oMinneapolis, Hennepin county, Minnesota, have invented certain new anduseful Improvements in Wrapping- Machines, of

which the following is a specification.

Wrapping machines as usually constructed utilize a plunger to stop thepackage for the differentoperations of wrapping, no provision being madefor centering the panels of the. label or obtaining an accurateregister. The friction of the package against the label is depended uponentirely to insure the position of the label and owing to slippage therelative position of the label and the package invariably changes duringthe wrapping operation. This shiftingof the label is not of so muchimportance in wrapping soap and similar articles, Where no accurateregister of the label panel is required, but in Wrapping cereal foodsput great waste in labels and damage to the.

up in rectangular packages it is necessary that the printed orlithographed panels of the label shall be accurately centered on thepanels of the package; otherwise the package will have an unfinishedlook and will not present a neat, ornamental appearance for displaypurposes on the store shelves. Furthermore, use of the' ordinarywrapping machine on labels requiring accurate work and perfect registerhas resulted in such a packages and the machines operate'at such acomparatively Islow speed that there is very little saving as comparedwith hand labor.

The object, therefore, of my present invention is to provide a wrappingmachine which can be operated at a comparatively high speed and whichWill wrap packages of cereal or other articles so that the panels of thelabels will be accurately centered on the'panels of the package andaperfect register maintained at all times between the package and thelabel.

A further object is to provide a machine in which the successiveoperations of gumming the label, registering the label with the packageand folding the label around the package will be carried on continuouslywithout checking the movement of the package or the label through themachine, l'

A further object is to provide av means for feeding the labels orwrappers positively and accurately, releasing them only when the packagehas been accurately centered on the label and the label partially foldedaround the package, so that the perfeet centering of the panels of thelabel with the panels of the package will be positively msured.

Other objects of the invention will appear from the following detaileddescription.

My invention consists generally in means for feeding the labels andmeans for feeding the article to be Wrapped into the path of the labelsand mechanism whereby the movement of the label and the article Will beaccurately timed so that the article and the label will registeraccurately at the initial stage of the wrapping operation.

Further the invention consists in mechanism controlled by the labelfeeding means for regulating the feed of article to' be wrapped.

Further the invention consists in means controlled by the position ofthe package or article to be wrapped for -regulating the operation ofthe feeding mechanism. Further the invention consists in a wrapthepackage or ping device and means for positively holding the label duringthe initial steps Iof the wrappmg or folding operation.

Further the invention consists in a wrapping or .folding mechanism whichwill accurately and smoothly fold the wrapper or label around thepackage or article.

Further the invention consists in various constructions andcombinations, all as herelnafter described and particularly pointed outin the claims.

In the accompanying drawings forming part of this specification, F igure1 is a plan view of a Wrapping machine embodying my inventlon, Fig. 2is'a side elevation of the same, Fig. 3 is alongitudinal sectional viewof the middle portion of the machine, Fig. 4

is a transverse sectional 'view'on the line X-Xof Fig. 3, Fig. 5 is asectional view of the receiving end of the machine showing the drivingmechanism, Fig. 6 is a plan section of the receivingr end of themachine, Figs. 7, 8 and 9.are detail views showing the operation of thegripper bars and means Ifor advancmg the labels in the machine, Fig. 10is a detail view showing the preferred manner of mounting the gripperbar mechanism, Fig. 11 is a view of the gripper bar jaws and thesupports for the same. Fig. l2 is a sectional view on the line -U of Fig.
